  1. Lead in Construction Training on the hazards of lead at construction worksites Developed by the Division of Occupational Safety & Health (DOSH) for employee training June, 2009

  2. Lead in Construction • We will cover the following topics: • Health hazards of lead • How you are exposed to lead • How to control your lead exposure • Respiratory protection • Medical monitoring • Medical removal • DOSH Lead standards 2

  3. Lead is hazardous to your health if it gets in your body. Here’s what it can cause: Headaches, tiredness and insomnia Loss of appetite and stomach pain Pain, weakness or twitching in your muscles Reduced sex drive and birth defects Kidney damage Permanent brain and nerve damage Health Hazards of Lead 3

  4. Health Hazards of Lead Lead is especially harmful to the fetus in a pregnant woman. Effects on Reproduction Lead is also harmful to men or women trying to have children. 4

  5. Health Hazards of Lead Children are very susceptible to effects of lead. The amount that can harm them is much less than adults. It is important not to take any lead dust home on your clothing. Effects of Lead on Children 5

  6. Health Hazards of Lead There is no real safe amount of lead, but there are levels that cannot be legally exceeded. This is called the “permissible exposure limit” or PEL. Is there a safe amount of lead? In the air: no more than 50 micrograms per cubic meter In your blood: no more than 40 micrograms per deciliter. Both these limits are in the DOSH regulations on lead. 6

  7. Lead “Action Level” When the amount of lead in the air is above the “action level” of 30 micrograms per cubic meter, we are required to: - Conduct air monitoring - Provide medical surveillance - Provide training The Action Level is 60% of the permissible exposure limit (PEL) 7

  8. How can lead get in your body? You can get lead into your body by: Inhaling lead dust or lead spray paint, Inhaling lead fumes from welding or burning lead paint, Swallowing lead dust on your hands from eating, drinking or smoking. 8

  9. Some Jobs Where You Could be Exposed to Lead Steel bridge painting or repair, Removing lead-based paint on old buildings or houses, Grinding or sandblasting lead paint on metal structures, Cutting or removing lead pipe in old buildings, Using solder that contains lead. 9

  10. Lead Paint on Bridges 10

  11. Bridge paint removal in an enclosure Work done inside this enclosure 11

  12. You work around lead at this jobsite in the following activities or locations: [Describe or list specific jobs or activities where employees are or may be exposed to lead at your worksite here.] 12

  13. The following products used or objects found on this worksite contain lead: 13

  14. We conducted and will continue to conduct air monitoring of lead in the air by attaching an air sampling device to employees working around lead like the photo on the right . You have the right to observe this monitoring. Results of our air monitoring are as follows: Air Monitoring 14

  15. Warning signs are posted at the entrance to any area where the levels of lead exceed the DOSH permissible limits. No one can enter these areas without a respirator or protective clothing. Warning Signs Warning Lead Work Area Poison No Smoking or Eating 15

  16. What personal protective equipment is needed? coveralls work shoes gloves respirator 16

  17. Types of Respirators for Lead In some jobs involving lead exposure, you may need a respirator. The type of respirator worn depends on the amount of lead in the air. We will provide you with the proper respirator and provide medical evaluations, fit-testing, and additional training 17

  18. Respirator Requirements The type of respirator that must be used depends on the level of lead in the air: A half-face cartridge respirators provides protection to levels 10 times above the permissible limit for lead. A powered air purifying respirator (PAPR)can provide protection from 25 to 1000 times above the permissible limit depending on the manufacturer and how it is designed. 18

  19. Using Respirators Respirators must be worn at all times when the amount of lead in the air is above the legal limit. Respirators must fit properly to prevent leaks. You must have a respirator medical evaluation before you wear a respirator. 19

  20. Respirators Must Fit Properly You must have a respirators with cartridges fit-test before you can use them. You can’t have a beard when you wear a tight-fitting respirator. We will train you on how to use your respirator. 20

  21. Respirators required at this jobsite [Describe or show the respirators required here.] 21

  22. Work Practices to Reduce Lead Exposure There are several ways you can reduce your lead exposure: Always wear your respirator in the areas where it is required, Don’t eat, drink or smoke in the area where there is lead, When you take a break, wash your hands before eating, drinking or smoking. 22

  23. Work Practices to Reduce Lead Exposure Use separate work clothing, and boots, Keep your street clothing in a clean place, Don’t wear your work clothing or boots home, Launder clothing at work. 23

  24. More work practices to reduce lead exposure Don’t remove dust by blowing down or shaking out your clothing. Take a shower or wash your hands and face at the end of the shift when required. 24

  25. Don’t dry sweep or blow down dust containing lead, What are some other work practices? Use a high-efficiency vacuum to clean up lead dust. Use water when grinding, sanding or cutting objects containing lead, 25

  26. Other methods of controlling lead dust Natural or exhaust ventilation can reduce lead levels in buildings or confined areas. or Exhaust fan Some grinders and sanders have exhaust ventilation attached. 26

  27. [List specific jobsite controls and work practices here] What controls and work practices we use to reduce your lead exposure 27

  28. Anyone who is exposed to lead above the “action level” must be provided blood tests. If the amount of lead in your blood is more than 40, we will send you for a medical exam. Blood tests will be routinely done if you are exposed to lead for 30 or more days per year. What medical monitoring is needed? 28

  29. More about blood sampling After the first blood sample is taken, we must take more 3 more blood samples for the next 6 months – every two months. After that, we must take blood samples once every 6 months. If the level in your blood exceeds 40, we must continue to take blood samples every two months until it drops below 40. Blood samples are taken at no cost to you and you will be notified of the results. 29

  30. Blood Lead Levels 30

  31. More about medical exams If the amount of lead in your blood exceeds 40, you will provided with complete medical exams by a doctor, annually. You can request an exam or review of the findings by a second doctor. We do not see the entire medical exam report, only the blood test results and whether or not you have a medical condition that precludes you from working around lead or wearing a respirator. 31

  32. Our Medical Surveillance Program Describe the details of your specific medical surveillance program here 32

  33. If the amount of lead your blood is above 50, you will be temporarily removed from the lead job. You can’t return to that job until your blood level drops below 40. Your blood must be tested monthly until the lead level drops below 40. Medical Removal for Lead Exposure 33

  34. Why is medical removal required? Medical Removal Medical removal is required is because of the serious health effects of lead. Your body will gradually rid itself of lead over time. You do not lose any earnings, seniority or benefits and you can return to former job status when blood lead levels drop. 34

  35. “Chelation” is the taking of certain drugs that help rid the body of lead. It is a form of treatment for high lead levels in the body. It is not allowed on a routine basis. Only a doctor can authorize and supervise lead chelation. What is lead chelation? 35

  36. You have the right to see any of your medical records related to lead. You also have the right to see results of our air sampling for lead. Medical and Air Sampling Records 36

  37. DOSH lead regulations for construction is found in the construction safety standards. It contains much more information in detail. A copy of this standard is available. DOSH Lead Regulations for Construction Click on image above to link to rule More information on lead 37
